Abstract

The invention provides an amputated upper limb movement neurological function recovery method. The method includes the first step of selecting a target muscle in the body of an upper limb amputee, and the second step of implanting main nerves and branch nerves of brachial plexus, needing to be rebuilt, of the stump end of the upper limb amputee into the target muscle. Through the amputated upper limb movement neurological function recovery method, strong myoelectricity information can be generated. The invention further provides a method for rebuilding a nerve-prosthesis interface.

Description

technical field [0001] The invention relates to a method for reconstructing the motor nerve function of the amputated upper limb and a method for reconstructing the interface between the nerve and the artificial limb. Background technique [0002] In recent decades, electromyogram (EMG) signals recorded from the surface of amputees' residual limbs have been widely used in the control of artificial upper limbs. Utilizing the direct relationship between EMG signals and body movements, the control of prosthetic limbs is realized through motors, which is expected to provide a multifunctional, intuitive (bionic) control prosthetic system for amputees. Current myoelectric prosthetics use myoelectric signals generated by a pair of residual muscles (primary contractor muscles and antagonist muscles) to control a degree of freedom of movement. Unfortunately, after amputation, the source of myoelectric information is limited. The higher the degree of amputation, the less residual lim...
